Hi

I have a GS300 Oct 2000 model, Purchased in Dec 06. It's been perfect up to mid April 07. The problem I am having is that if the car is left overnight and I come to switch it on in the morning, once the key is turned to the "START" position, absolutely nothing happens. It's as if the battery is completey dead but the dash board and stereo come on, ariel goes up etc. I take out the key and try again and it starts just fine and will be fine for the whole day. This has been happening every day for last 2 weeks. On 1/5/07 happened twice, I do have the odd day when this problem does not occur.

I have changed the battery for a new one (the correct one as advised by a Lexus Technician after they spent 3 hours trying to track the fault but couldn't find it) but that has had no effect. I also do notice an extended humming/buzzing noise coming from the engine, have not noticed it before!

Anyone have any idea's to why it is doing this?
